Long Post:

I attended September off-campus on-site drive at their ZOHO office Chennai. This hiring was there for developer position in their ZOHO mail team.

Round 1: Aptitude + C

• Happened on 2nd September at 11:30 to 12:30 AM in their parking space.
• 10 basic aptitude and 15 C coding/output related questions. No multiple choice, you are supposed to write correct answer in front page.
• The results were declared after half an hour and only 26 people were shorlisted. Rejected candidates were told to leave and try again after 6 months.

My opinion: I don't find it practical at all to call candidates in large numbers to just reject them immediately on spot. People have to spend time, energy and money to come to these drives. I could feel the disappointment in the air when they announched the shortlist. Seeing those many hopeless faces was not cool. It's clear from their actions that they want best out of best so why don't just call worthy candidates.

Round 2: Basic Coding

• This round happened after lunch the same day, I don't remember the time but it went for 1 hour. All the further rounds were supposed to be coded on their systems only.

• The following questions were asked with links

268. Missing Number

171. Excel Sheet Column Number

I don't have link to 3rd problem so here is the statement, there are two words, secret word and guess word, for each letter in guess word if it matches exactly with secret letter print g, if letter is present at differnt positoin print y, if letter is not present at all print -(hyphen).

Example -
secret - BRICK guess - BLOCK, output = g--gg

392. Is Subsequence

• Since all questions are easy rated, this round can be cleared with basic knowledge of coding.

• Us 13 candidates went to next round.

Round 3: Advanced Coding

• This round again happened on same day and we were given 1 hour to code.

• The following questions were asked with links

121. Best Time to Buy and Sell Stock

2428. Maximum Sum of an Hourglass

1525. Number of Good Ways to Split a String

• Us 9 candidates went to next round

My Opinion - if they had to shorlist few people out of small number of people then why don't directly ask these medium level question. Anyways

Round 4: Console Application

• Only one problem statement was given, I have given gist of statment below.

Part 1:

• This round happened on 7th September, we were called at morning 9:30. The round went from 10:30 to 2:00 PM.
• During this round 5 candidates were informed to leave.

Part 2:

• This round went from 3:00 to around 6:00, we were told to continue implementing the same problem statemnt.
• The issue was that problem statment was not very clear with requirements and the invigilators themselves couldn't come up with a valid explaination for the input and output cases.
• By 5 PM my soul had already left the body but we were still implementing what we can.

Problem statement:
Implement Parking lot system that is responsible for assigning floor and slots for cars and maintain a queue for cars. (Sounds simple right, you have not read the functional requirements)

Below I have just mentioned modules we worked with

• Car registration module.
• User registration module.
• Parking system module. (Shit hit the roof on this one.)
• Cost calculation module.
• Report registration module. (Only if someone could reach till this point.)

Finally

By 6 PM they informed they are not moving forward and we were informed to leave. I talked with another candidate who had appeared multiple times. The rumor I got from inside is that they hired through referral.
